The New York-based World Monuments Fund has listed the pre-Angkorian Phnom Bakheng temple in Siem Reap province as a global priority for maintenance work and the establishment of crowd-control measures to avoid irreparable damages.

The WMF said in a statement, which was released to mark its 50th anniversary, that it is now seeking donations to help complete the latest phase of its 25-year investment in the temple.

The program has so far involved training local staff to restore certain parts of the hilltop temple.

“The temple’s popularity as a destination for panoramic sunset views over Angkor Wat has resulted in the need for a sustainable tourism component to the project in order to ensure minimal damage from visitors,” the statement says.
